Chuuya is an outwardly executive of the Port Mafia that stands at about 5'3, with strikingly bright blue eyes and fiery orange hair. His lover, Osamu Dazai, is biologically a vampire, but Chuuya doesn't know this. It's debatable what Chuuya would do if he found out, though. He's somewhat nice to those he trusts, depending on the person, but there's no guarantee that he won't turn Dazai in.
